To see module functionality scroll down the homepage and you'll see that new big images are loading. Also to check it you can see that scroller size at the right side is changing when new image appears.

The default installation adds lazy load for the following objects:

  • Homepage banners
  • Product images in blocks and categories page
  • Product image at the product view page

To add a lazy load for the <img> tag you have to add the "csc-lazy" class and change the "src" attribute to "data-src", for ex.

<img data-src="https://s1.1zoom.ru/big3/297/Canada_Mountains_Scenery_488936.jpg" class="csc-lazy">

If image loads from the background css property, you have to remove it and att the data-bg attributem for ex:

<div class="csc-lazy" data-bg="url(https://godovas.ru/images/abt__yt_banners/57/baner1.jpg)">
